ANTIREFILLING BOTTLE.

SPECIFICATION forming part of Letters Patent No. 576,263, dated February 2, 1897. Application filed February 20, 1896. Serial No. 580,028. (No model.)

T0 aZZ 1072,0127, it may concern.-

Be it known that I, CEPHAS GILBERT, a citizen of the United States, residing at Branford, in the county of Suwannee and State of Florida, have invented a new and useful Antirefilling Bottle, of which the following is a specification.

The invention relates to improvements in antirefilling bottles.

The object of the present invention is to improve the construction of antirefilling bottles,to increase their simplicity and efficiency, and to provide an inexpensive one which will effectually prevent the introduction of a liquid into it after it-has received its contents, and which will be entirely useless after its original contents have been decanted.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

I11 the drawings, Figure 1 is an elevation of a portion of a bottle constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail view of the ball-valve.

Like numerals of reference designate correspondin g parts in all the figures of the drawlngs.

1 designates a bottle provided on the interior of its neck with an annular rib 2, formed by creasing or constricting the neck when the glass is in a heated condition and providing an exterior annular groove 3. The rib 2 has its upper inclined face ground to form a valveseat 4 and receivinga ball-valve 5,constructed of glass or any other suitable material and having a limited movement to and from the valve-seat to permit the contents of the bottle to be decanted when the bottle is in an inverted position. Then the bottle is arranged in an upright position, the ball -valve fits snugly on the seat 4, closing theneck of the bottle and effectually preventing the introduction of a liquid into the latter.

The ball-valve-is retained in proper position in the neck of the bottle by a pair of spring-arms 6, provided with straight parallel upper portions 7 and having oppositely-disposed outwardly-extending V-shaped lower contents the ball-valve is introduced into the neck and the V-shaped lower portions are adapted to spring inward automatically When they engage the valve-seat, to pass the same, and to permit the valve to rest thereon, and the spring-arms will prevent the ball-valve from leaving the neck of the bottle, as before explained. 7

It will be seen that the antirefilling bottle is exceedingly simple and inexpensive in construction, that it is positive and reliable in operation, and that it will effectually prevent the introduction of a liquid into a bottle after the latter has received its original contents. It will also be apparent that the bottle will be absolutely worthless after its original contents have been decanted, that it cannot afterward be used in trade, and that the interior rib is readily constructed by grooving or constricting the neck of the bottle when the glass is in a heated condition. Furthermore, it will be apparent that the parts are readily assembled after a bottle has been filled.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What I claim is-- A non-refillable bottle provided within its neck portion with an annular rib 3having oppositely-inclined upper and lower faces, the upper face being ground to constitute a valveseat and the lower face forming a stop for the valve, a ball-valve or stopper consisting of aglass sphere having a single piece of springwire bent centrally to form a fl-shapedlconnecting portion 9 secured within the ball, parallel portions 7 projecting outward from said ball to permit limited movement to the valve, and the terminal ends of said wire being bent oppositely outward and then inward lOO' to form the spring-stops 7, said valve being In testimony that I claim the foregoing as designed for insertion Within the neck of the my own I have hereto affiXed my signature in bottle, and the Wire arms to be pressed inward the presence of two Witnesses.

to pass the rib 3 to permit a limited move- CEPHAS GILBERT. 1nent when the bottle is tipped and prevent lVitnesses:
